Hey guys,
So overnight, as soon as I woke up, my mobile network had the 0 with the cross through it. Everything on the phone cannot be used except for on WiFi as the "Mobile network is not available". I inserted and reinserted the SIM and there is no change. The phone was on my dresser all night and didn't move. Any ideas?
Also, when I went to do a factory reset nothing happened. Like, I hit DELETE ALL and it just sat there. I had to use ANDROID DEVICE MANAGER to do an Erase and it reset the phone but the signal bar is still the same. No SIM being detected. It was working perfectly fine yesterday.
Try somebody else's sim card. It might just be your sim. If you don't have another to try, go to AT&T and ask to test one of theirs. They'll probably give you a new sim card.

Ok, I'm going to give you guys the whole background story just to cover all the bases.
I've had a Nexus S for about 6 months, never had a hitch. Rooted it, etc etc all fine and dandy.
About two weeks ago, I updated it to CM 7.1 RC1. So far so good.
I've always had the same Vodafone SIM card, which has accompanied me through a couple of phones. Last week, I went to London and bought a UK pay as you go card, to use data without roaming. Perfect. No problems whatsoever.
So, to make it clear, I never had problems with my original (portuguese) SIM card, nor with the british one I had just bought.
However, it was upon my return that I realized I had forgotten my SIM card at my friend's house. I quickly stopped by the Vodafone store at the airport, where they promptly gave me a new SIM, ready to use within a couple of hours.
Since then, my phone after a short period of being on, spontaneously fails to detect the SIM card/no longer recognizes it. I've tried scanning for networks in the settings, but it won't let me register again. It takes a reboot to get it working. Thing is after a couple of minutes or hours, it happens again.
I have since exchanged the new SIM card with a newer one , also from Vodafone, albeit a different store. Yet, the problem persists.
I didn't alter any settings between Portugal-UK-Portugal, so everything should be exactly the same. Does anyone know how to solve this or why this happens?
Faulty phone?
Faulty radio?
Faulty SIM cards?
ROM bug?
Any help is appreciated.
I'm having a SIM card issue, but I'm not sure it's specific to the SIM or my phone. Here are the symptoms: my phone randomly loses all it's cell phone bars and 4g, and eventually says no SIM is seated in the device. It sometimes turns into emergency mode, but usually just shows no signal. If I restart the phone, everything comes back just fine for an indeterminate amount of time.
Assuming it was a bad SIM, I went to VZ and got a new one, but the exact same behavior continues to occur.
Any clue what this could be? I'm on 4.1.2.
Hello everyone,
My mother owns a Nexus 5. Some days back her phone hanged so we waited till the battery depleted and it turned off. On turning it on we noticed that the phone didnt get any network. Tried almost everything but nothing worked. Then I switched to a test sim and the phone could catch the network but didnt work again once I inserted my mom's sim. We got a new sim but the same issue ( test sim and actual sim are on different operators). Can anyone recommend a solution?
I have a Samsung Galaxy S3 (SCH-I535) that I was trying to resurrect as a WiFi hotspot and found that I have a couple of issues here that I never had before.
First off, I've tried putting in different SIM cards trying to activate it and the crazy phone will not read any of the SIM cards that I put in it. Before anyone asks, I did make sure that the card was installed properly. It doesn't matter if I put in a Verizon or Straight Talk SIM card. Neither one works. I always get the pop up box telling me that I need to insert a SIM card even though I have already put one in.
Second issue that I have been having recently is that anytime I take out the battery in the S3 (either to replace SIM card because it's easier to replace SIM card with the battery out of it) or to put in another battery, I lose the current date and time in the phone. Always goes back to noon on January 1st. This one is just pure irritating to me.
These issues just came up in the past few weeks and I'm tempted to just chuck the phone if I'm not able to get these issues rectified. Any help I can get on this would be greatly appreciated.

Sounds like you need to have the phone activated. Not sure about the SIM issue, but all phones get the time from the cellular network when they're powered up.

I've tried that but I still get the SIM Card message coming up even though I have inserted it. I thought that the phones get the time from somewhere and this week is the first time that I've had the issue with the phone losing the date and time once I change out the battery.

Goto Setting>More settings(in wireless and network tab) >Mobile Networks>Network mode

Hey guys. I have an unusual problem with my phone.
I was using my phone one night while in bed, playing a game that requires online connection when suddenly, my phone slipped from my hands. I managed to save it from falling to the floor, but it hit the wooden frame of the bed in the process. I checked the phone out and noticed no problem with it. The screen was fine, nothing broken on the exterior. So I tried to go back to my game, but it complained that there was no internet connection. That was when I noticed the signal had disappeared and the phone displayed "No service". I tried turning airplane mode on and off........nothing, restarted the phone.........no change. I turned off the phone and went to sleep.
In the late hours of the morning, I switched it on, and was greeted with the "emergency calls only" warning. I tried removing and re-inserting the sim card, restarting the phone and when I tried everything I could think of, I did a factory reset on the phone. Still, nothing changed. So, to rule out the possibility that the service was at fault, I removed the sim and inserted it into my brother's phone. It worked as it should! I inserted my brother's sim into my phone, same thing. At times, I get "No service", at times, "Emergency calls only", even some times, I get "No sim card", when there's actually a working sim card in the phone. These led me to believe the phone isn't detecting sim cards, but sometimes, the phone recognizes my sim card and the signal shows up, but I'm unable to use mobile data connection, make or receive calls or texts, or even dial a code to check my airtime balance.
So I decided it was definitely the hardware that had developed a fault. But then, one day, I went to visit a friend quite far away from where I lived, and I took my phone with me. To my surprise, my phone worked flawlessly there. I was able to use data connection and was getting good speeds. I was able to call and text. I removed the sim and put in another sim and it was the same.........worked flawlessly. Now, I don't know what to think anymore because as soon as I got back home, I was again getting the No service/Emergency calls only warnings, and the same sims work in my brother's phone - my brother lives with me.
** I know (or think) it's not a software problem because it would have been resolved after I hard reset it. Plus, it all started when it hit the bed.
** I know it's not the service in my area because the sim works in my brother's phone and my brother stays with me.
** I can't decide if it's an hardware problem because sometimes it works, sometimes it doesn't.
Some facts about the phone (if it helps)
** The phone is rooted
** It uses a sim tray. The type that allows two micro-sims or one micro-sim and one sd-card.
** The phone gets hot when I use it extensively.
I'd appreciate any help. Thanks guys.
